Homemade pyrotechnics. May involve the use of fuel, lighter fluid, welding gasses, household cleaners, or black powder intended for use in muzzle-loading firearms. Generally lit with cigarette lighters, matches, lit cigars or cigarettes, or -- in rare cases -- electrically lighted with the use of either a car battery or household current. Dangerous as hell.
One of the more common forms of redneck firearms is the use of reactive metals in a 20-ounce soda bottle, known as an acid bomb
, dry-ice bomb
, or Drano bomb
. Another is the trapping of a gas, such as butane or acetylene in a pipe or a series of beer cans with the tops and bottoms cut out, held together with duct tape, which when lighted makes a loud noise and can be used to hurl projectiles, such as tennis balls, potatoes, or garbage, into the neighbors' yards.

or dorm cannon
